I wouldn't have downvoted this comment...because it actually refers to the report at hand and directly critiques it. I'm not anti-anti-fracking, just anti-anti-anti-fracking generalizations.
Also this "A 2009 ProPublica investigation found that contamination was far more prevalent than indicated in the report, citing more than 1,000 cases tied to drilling and fracking that had been documented by courts and state and local governments." http://www.sourcewatch.org/index.php/Fracking_and_water_poll...
